Switzerland was without the country's two best players this weekend: 18-time Grand Slam champion Roger Federer and three-time major champ Stan Wawrinka. Federer won the Australian Open last Sunday night.

The U.S. will travel to Australia for the April quarterfinals. Australia advanced with a 3-0 victory over the Czech Republic.

The Americans are now 158-4 all-time in Davis Cup ties when taking a 2-0 lead. Sock also won a singles match on Friday. Reverse singles will be best-of-three Sunday.
